Climate Change And Other Pollution

Reference

The bad news is EVs won't help in time to keep global warming below +2.0oC, or reduce emissions in the critical years up to 2040. The EV transition means things still get worse before they get better, until late as 2050. The problem is not the 'long tailpipe argument', but the challenge of the transition to EVs. EVs do, over their lifetime, result in a reduction in emissions, but the whole process can take decades, does not alone solve immediate climate problem. Emissions can even be worse if too many people buy EVs too soon.

Moving to EVs is going to increase electricity requirements, and at a time when there is already a technical challenge to more the electricity supply to "green" source. But what it electric vehicles could solve the "green power grid" problem, provide energy security, and avert a threat of increasing inequality? It turns out dream scenario is definitely possible, but can be fully realised only if the home charging problem be solved.

At least, not alone. Solar and Wind have proven to be successful partial cost effective substitutes for fossil fuels, neither wind nor solar is stored energy. Without strategies and adding stored energy available on demand, it is impossible to reach the goal of removing reliance on fossil fuels.

Consider home solar. With solar panels you can reduce your electricity costs, but to go 'off grid', you need a battery or other energy storage for the solar power. Yet, the need energy storage is being installed, but not connected to the grid.

The EV climate change lag problem: Don’t buy an EV just to save the planet.

The bad news is EVs won’t help in time to keep global warming below +2.0oC, or reduce emissions in the critical years up to 2040. The EV transition means things still get worse before they get better, until late as 2050. The problem is not the ‘long tailpipe argument‘, but the challenge of the transition to EVs. EVs do, over their lifetime, result in a reduction in emissions, but the whole process can take decades, does not alone solve immediate climate problem. Emissions can even be worse if too many people buy EVs too soon.

Big Oil, AKA Big Fossil: How real, and what about ‘big climate’?

It is clear that significant funding is directed to promoting the continued use of fossil fuel.

Time after time I find the need to make this claim, and as I do not make claims without supporting evidence, so each time it triggers a search for supporting evidence.

I have now decided to create a page with links to supporting evidence, as an improving over multiple pages each linking directly to one or two pieces of the puzzle.

For balance, I examine the idea of ‘big climate’ or ‘big science’, being a source of funding bias data applied against the arguments of ‘big oil’.

Home Charging: The Challenge To A Green Equitable EV Transition

Moving to EVs is going to increase electricity requirements, and at a time when there is already a technical challenge to more the electricity supply to “green” source. But what it electric vehicles could solve the “green power grid” problem, provide energy security, and avert a threat of increasing inequality? It turns out dream scenario is definitely possible, but can be fully realised only if the home charging problem be solved.

COP26: Were The Deck Chairs Sufficiently Shuffled?

COP26. It sounds like a police officer who can’t be named. For me it raises questions such as:

  • Why “COP26” and what happened to the first 25 COPs?
  • Are all decisions are made in advance, or is anything really agreed at the conference?
  • Is there more than politicians and fossil fuel companies agreeing spin and token gestures?

Solar and Wind: Renewables alone not a substitute for fossil fuels.

At least, not alone. Solar and Wind have proven to be successful partial cost effective substitutes for fossil fuels, neither wind nor solar is stored energy. Without strategies and adding stored energy available on demand, it is impossible to reach the goal of removing reliance on fossil fuels.

Consider home solar. With solar panels you can reduce your electricity costs, but to go ‘off grid’, you need a battery or other energy storage for the solar power. Yet, the need energy storage is being installed, but not connected to the grid.
